The epidemiological studies and clinical features of Schistosoma hermatobium were carried out on 100 pupils of Local Education Authority (L.E.A) Primary School in Giri Village, Abuja. The result of this study showed a total prevalence rate of 33%. The prevalence of Schistosoma hermatobium in relation to gender showed that the male pupils 33.9% were more infected than the female pupils 31.8% But there was no significant relationship between prevalence and gender (p> 0.05). However, the prevalence rate in relation to age group showed that age group 14-16 had the highest rate of prevalence (43.5%). Statistical analysis also showed that there is positive correlation between prevalence and the various age groups (p<0.05). This study showed that Primary six pupils had the highest prevalence of Schistosoma hermatobium in relation to class of study. (37.7%). However, there was no positive relationship between prevalence and class of pupil (p>0.05). This study reveals that Schistosoma hermatobium parasite is a concern in Giri area, Abuja, FCT. Therefore, this study recommends that the government should create awareness on the impact of this disease and to enlighten the children through health education programs on the mode of transmission of this parasite and how to control Schistosomiasis.

In recent times, the heavy metals pollution in the environment through soil, plant and air has increasingly gathered global concern. The aims of this study is to determine the heavy metals concentrations in the root, stems and leaves of Moringa oleifera plants and the soil sample of Potiskum metropolis as the plant is widely getting popularity and acceptance for used medicinally to cure different ailments in humans and also to compute the translocation factor from different sites. The heavy metals such as (lead, cadmium, zinc and iron) were determined using Atomic Absorption Spectrometry method. Results from different sample of M. oleifera showed the highest mean concentrations of the following heavy metals from different parts of M. oleifera , for cadmium root (Jigawa Cd= 0.007±0.001 ppm),lead leaves (Nahuta Pb = 0.100 ±0.021 ppm), Zinc and Iron from the leaves and stem of samples (Arikeme Zn = 0.063±0.001 ppm and Fe =2.464±2.393ppm) respectively. Also, the soil samples, with the highest mean concentrations of cadmium and lead was obtained from Jigawa soil and were (Cd = 0.007±0.000 ppm and Pb = 0.080±0.009 ppm) respectively. Also for the Zinc and Iron recorded at Mamudo soils were (Zn =0.032±0.014 ppm and Fe= 5.468±0.753 ppm) respectively. Moreover, the translocation factor (Tf ), for the Cd in all the study areas were recorded (Tf ≤1) except in Jigawa (Tf ≥1), the lead Tf values reported for all study sites was (Tf < 1) and that of Arikeme site (Tf ≥1). While for the Zn and Fe Tf values of all study sites were recorded reciprocal as (Tf ≥1) and (Tf ≤1) respectively. It was concluded that the heavy metals in M. oleifera plants and soil samples of all the study areas are safe for humans as outlined by FAO/WHO.

Argenome mexicana Linn. (Family: Papaveraceae) is traditionally used to relieve inflammatory and pain-related health conditions. It is also used as laxative. The intraperitoneal median lethal dose (LD50 ) of the methanol extract was determined in mice. The methanol extract of the plant was 50 evaluated for antinociceptive effect using acetic acid-induced writhing test in mice and formalin induced pain test in rats. Fresh egg albumin-induced oedema model was used to test for its antiinflammatory effect in rats while the gastrointestinal effect was tested using gastrointestinal motility (transit) model in mice. The intraperitoneal LD value in mice was calculated to be 894.4 50 mg/kg. The extract (75, 150 and 300 mg/kg i.p) significantly (p< 0.05) and dose-dependently inhibited acetic acid-induced pain with the values of 44.83%, 68.97% and 81.38% respectively. Acetyl salicylic acid (ASA; 150 mg/kg i.p) also significantly (p<0.05) inhibited pain with inhibitory value of 65.52%. The extract (75, 150 and 300 mg/kg i.p) significantly (p< 0.05) and dose-dependently inhibited the early phase of formalin-induced pain with values of 56.76%, 75.68% and 78.38% respectively. The extract at the same doses also inhibited the late phase of formalin-induced pain in a dose-dependent manner with the values of 39.51%, 55.56% and 74.08% respectively. The late phase inhibition was only significant (p<0.05) at the doses of 150 and 300 mg/kg i.p. The magnitude of pain inhibition by the extract was higher in the early phase. The extract (75, 150 and 300 mg/kg i.p) produced a dose-dependent inflammatory inhibition with percentages of 15.00 %, 25.00 % and 73.34% respectively. ASA (150 mg/kg i.p) produced 36.67% inhibition. The extract produced gastrointestinal movement inhibition of 54.70%, 55.47% and 73.32% respectively. The inhibition was significant (p < 0.005) only at 150 and 300 mg/kg i.p while atropine (0.1 mg/kg i.p) produced a significant (p < 0.05) inhibitory effect with percentage of 63.94%. The study provided scientific justification for the traditional use of A. mexicana in pain and inflammatory health conditions but did not justify its use as a laxative.

Amoebiasis is one of the major causes of morbidity and mortality worldwide, especially in developing countries because of lack of safe portable water and low level of hygiene. In Nigeria, amoebiasis is prevalent and widespread. The aim of our study was to estimate the prevalence ratio of E. histolytica among infants aged 1 to 59 months admitted at the University of Abuja Teaching Hospital, Gwagwalada, Abuja. The distribution of the infection was reported to relate more with inadequate environmental sanitation, poor personal hygiene and climate. The epidemiology, clinical features and causative agents of diarrhoea were investigated in 100 children aged 1-59 months visiting the University of Abuja Teaching Hospital. One hundred stool samples were collected and examined. The use of direct smear and floatation methods were employed to analyze the prevalence of Entamoeba histolytica in diarrhoeal illness across gender, age, weight and stool appearance of the patients. Out of the one hundred stool samples screened 12% were positive for the parasite. Females were more infected (12.5%) than the males (11.4%), but there was no significant association between prevalence and gender (P>0.05). Children within the age group of 1 to 12 months old had the highest prevalence rate (20.0%). There was a significant difference in the prevalence of Entamoeba histolytica among the age groups (p< 0.05). Children that weighed less than 15kg had the highest prevalence of Entamoeba histolytica (25.0%). There was a positive correlation between the prevalence and weight (p<0.05). Prevalence rate of 16.0% was recorded for watery and bloody stool. There was a positive correlation between the prevalence of Entamoeba histolytica and stool characteristics (p < 0.05). Hence this study analyzes the pattern, morbidty, occurrence and the preventibve measures to enact in tackling diarrhoeal illnesses. This study also aims to enlighten the public especially nursing mothers on the need to maintain proper hygiene in other to prevent contamination of diarrhoeal illness. Entamoeba histolytica can be a re-emerging serious infection when it finds favorable environmental conditions and host factors which are mainly attributed to poor hygiene in this study. This may occur in any area of the world with the same risk factors. Owing to the findings of this research, public health interventions such as the provision of clean water, community health education, observation of food hygiene, and maintenance of functioning sanitation systems are recommended towards controlling the infection.

Several plants are found to possess potent medicinal and phytochemical compounds used globally for the treatment of diseases and the discovery of new drugs. Plants with anthelmintic properties have attained a great interest due to their usage in treatment of parasitic (helminthic) diseases that cause major economic loss, resulting to reduced livestock production capacity of farmers. The major impediment in the livestock subsector is the increasing problems of development of resistance to synthetic drugs by the helminths and or high cost of commercially produced anthelmintics and their resultant side effects than the treatment efficacy in the host. Helminthosis is a clinical condition that represents one of the commonly encountered and most important diseases in ruminant farming. This clinical condition is aggravated by indiscriminate use of anthelmintics in an attempt to control the infection, thereby causing resistance of the parasitic helminths to synthetic drugs. This has led to the screening of plant extracts for their anthelmintic properties thereby serving as alternative strategies against gastrointestinal parasitic resistance. However, eighty percent of the world populations use natural plant compounds as anthelmintics for treatment of parasitic infections. Hence, the folkloric claims of the anthelmintic properties of plants extracts for the treatment of helminthes is necessarily important and of great interest. Therefore, this review unveils previous pharmacological and preliminary studies on plants as anthelmintics able to reduce helmintic infections and overcoming helminth parasite resistance.

The brain is one of the most important organs, as it controls numerous bodily functions. Due to its crucial regulatory roles, the nervous system of fishes and especially the brain needs more research. Catfish (order Siluriformes or Nematognathi) are ray finned fish, named for their prominent whiskers (barbels), which resembles the whisker of a cat. The Nigerian cultured catfish (Clarias gariepinus) have small eyes and wide mouths, which suggest low dependence on vision, nocturnal activity, and predatory habits. Herein, we describe the gross morphology and morphometrics of the brain of Clarias gariepinus. Five apparently healthy adult catfish (Clarias gariepinus) without sex differences were used. Cranial nerves and spinal cord were severed as the brain case was removed, after which all the morphological descriptions were done. Ten morphometric parameters were also measured. The generated data were graphically illustrated with scatterplot and biplot, as well; the regression analysis showing the stepwise fit for the prediction of the brain weight from other measured parameters was also presented. The olfactory bulb is large, somewhat rounded and rostral. The cerebellumin all examined brain was the largest structure of the brain with a cerebellar length and width of 1.16±0.11 cm and 0.82±0.03, respectively. The optic tectum, lobusvagi, lobusfacialis and eminentiagranularis were also well developed but small in size. Although, the behavior of the catfish (Clarias gariepinus) is still unknown, the relative proportion of the cerebellum, optic tectum, eminentiagranularis, lobusfacialis and lobusvagi, might be related to carnivory and an enhanced capacity for food selection in this species. In conclusion, the report herein has helped to provide useful information for the first time on morphology of the brains of Clarias gariepinus cultured in Nigeria, for understanding of the neurobehaviour and habits of this species.

As part of the several efforts to understand the biology of the African Giant rats (AGR) (Cricetomys gambianus), seasonal changes in the gonadotropin and testosterone levels of the adult male African giant rats of about 1 – 1½ years of age in captivity were investigated during wet and dry seasons in the tropics. Male giant rats (n = 10) were kept for 12 months and blood samples were collected monthly (on 15th of each month), during the dry (November – February) and wet (March – June) seasons for Luteinizing hormone (LH), follicle stimulating hormone (FSH) and testosterone assays. The hormones’ levels were evaluated to suggest the best breeding season for giant rat in South-West Nigeria. The result showed that there were significant variation (p<0.001) in LH and FSH levels in the giant rat in the wet season when compared with the dry season. However, testosterone level was significantly lower (p<0.001) in the wet season than in the dry season. The study showed that sexual activities in the male AGR might be higher in the dry season with peak activities in December in the tropics while the gonadotropins prepare the animals for sexual activities in the dry season. Further studies on the seasonal activities of gonadotropins in the female will give more insight into the sexual receptivity and performance in these animals.

The result showed that there were significant variation (p<0.001) in LH and FSH levels in the giant rat in the wet season when compared with the dry season. However, testosterone level was significantly lower (p<0.001) in the wet season than in the dry season. The study showed that sexual activities in the male AGR might be higher in the dry season with peak activities in December in the tropics while the gonadotropins prepare the animals for sexual activities in the dry season. Further studies on the seasonal activities of gonadotropins in the female will give more insight into the sexual receptivity and performance in these animals.","PeriodicalId":17442,"journal":{"name":"Journal of Veterinary and Biomedical Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88617450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluated the effects of dietary aflatoxin B1 (AFB ) exposure on the immune response and the 1 growth performance of Heterobranchus longifilis catfish; and determined the maximum tolerable limits for AFB in H. longifilis. Five experimental isocaloric and isonitrogenous diets amended 1 with varied concentrations of AFB [Diet A (2.0 μg AFB .kg-1); Diet B (7.3 μg AFB .kg-1); Diet C 1 1 1 (17.6 μg AFB .kg-1); Diet D (48.0 μg AFB .kg-1) and Diet E (93.0 μg AFB .kg-1)] were fed to 450 1 1 1 juvenile H. longifilis in five groups of 15 separate plastic tanks for a period or 56 days. At time points day 7, 14, 28 and day 56, five fish were randomly sampled per tank and assessed for innate immunity and growth response. Fish fed diets amended with AFB exhibited significant reduction 1 (P < 0.05) in the serum lysozyme and epidermal mucus lysozyme activity, epidermal mucus alkaline phosphatase activity and in the phagocyte respiratory burst activity. These parameters decreased with increasing concentrations and duration of dietary AFB (P< 0.05). Dietary AFB 1 1 caused significant reductions in the growth performance of juvenile H. longifilis marked by reductions in the percentage gain in length, reduction in percentage gain in weight and a reduction in the specific growth rate. Based on these results, juvenile H. longifilis catfish appears to tolerate diets containing up to 17.6 μg. Kg-1 AFB in diets.

Fasciolosis is a parasitic disease affecting ruminants. The aim of the study was to determine the prevalence of Fasciola gigantica in sheep and goats in Zaria, Kaduna State. A total of 400 faecal samples were collected over a period of three months (July to September, 2018) and examined using the formal ether sedimentation technique. The overall intensity of the infection was one plus(1+) indicating low infection. The prevalence of F. gigantica in the small ruminants examined was 52(13.0%) with sheep having a higher prevalence of 34(17.0%) than in goats 18(9.0%). Higher prevalence of F.gigantica was also observed in adult sheep 28(22.2%) and goats 15(20.0%) than in young ones of sheep 6(8.1%) and goats 3(2.4%).Consequently, higher prevalence of F. gigantica was observed in female sheep and goats with respective prevalence rates of 23(24.2%) and 17(12.1%) than in male sheep and goats with rates of 11(10.5%) and 1(1.7%) respectively. The prevalence of F. gigantica was 8(21.6%), 23(17.0%) and 3(10.7%) for Uda, Yankasa, and Balami breeds of sheep respectively, and 17(10.4%) and 1(2.7%) for Kano Brown and Crosses of goats respectively. Higher prevalence of F. gigantica was observed in ruminants on non-settled farms 37(18.5%) than those on settled farms15(7.5%).The prevalence of F. gigantica was significantly (p<0.05) higher in animals with poor body condition 18(34.0%) than good body condition 1(1.8%) animals. This study has established the presence of F. gigantica in faecal sample of sheep and goats in farms within Zaria, therefore appropriate use of anthelmintics and awareness of the public on the prevention and control measures should be ensured.

The scientific investigation of the folkloric use of Hermannia geniculata roots in the management of diabetes mellitus was conducted. Phytochemical analyses, in vitro antioxidant and hyperglycaemic studies were carried out on the crude extracts of H. geniculata. Qualitative phytochemical analysis revealed the presence of saponins, phenols, flavonoids, alkaloids, tannins, phytosterols, triterpenes and anthraquinones. The ethanol extract exhibited the highest free radical scavenging capability with the lowest IC values (0.52, 0.38, 0.59, 0.63, 0.39) mg/mL for 50 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2-Azino-bis(3-ethylbenzothiazoline-6-Sulphonic acid (ABTS), hydroxyl radical, superoxide anion radical and metal chelating ability which is significantly different (p<0.05) from the standard (silymarin). In antidiabetic studies, ethanol extract is a potent inhibitor of α-glucosidase (IC : 0.15 mg/mL) which is lower and significantly 50 different (p<0.05) from the standard (acarbose) IC value of (0.52 mg/mL). Ethanol extract 50 exhibited a milder inhibition of α-amylase enzyme with IC (0.57mg/mL) which is higher and 50 significantly different (p<0.05) from acarbose with IC (0.47 mg/mL). Kinetic studies revealed H. 50 geniculata ethanol extract exhibited competitive inhibition of α-amylase and uncompetitive inhibition of α-glucosidase enzymes. All these findings provided the scientific basis which support the use of the root extract of H. geniculata in the management of diabetes mellitus and oxidative stress induced ailments like colitis and ulcers by the Basotho traditional medicine of South Africa.
